NOTES

* Use only compact discs bearing the

mark.Do

not play heart-shaped, octagonal, or other specially shaped

compact discs.

Some CDs recorded in CD-R/CD-RW mode may not be

usable.

* We cannot supply PWB with component parts in principle.

When a circuit on PWB has failure, please repair it by

component parts base. Parts which are not mentioned in

service manual are not supplied.

* Specifications and design are subject to change without

notice for further improvement.

DRZ9255

To engineers in charge of repair or in-

spection of our products.

4. Caution in removal and making wiring connection to the

parts for the automobile.

Disconnect the battery terminal after turning the ignition

key off. If wrong wiring connections are made with the

battery connected, a short circuit and/or fire may occur. If

extensive damage is caused due to negligence of repair,

the legal responsibility shall be with the repairing company.

5. Cautions regarding chips.

Do not reuse removed chips even when no abnormality is

observed in their appearance. Always replace them with

new ones. (The chip parts include resistors, capacitors,

diodes, transistors, etc). The negative pole of tantalum

capacitors is highly susceptible to heat, so use special care

when replacing them and check the operation afterwards.

6. Cautions in handling flexible PWB

Before working with a soldering iron, make sure that the

iron tip temperature is around 270 . Take care not to ap-

ply the iron tip repeatedly(more than three times)to the

same patterns. Also take care not to apply the tip with force.

7. Turn the unit OFF during disassembly and parts replace-

ment. Recheck all work before you apply power to the unit.

8. Cautions in checking that the optical pickup lights up.

The laser is focused on the disc reflection surface through

the lens of the optical pickup. When checking that the la-

ser optical diode lights up, keep your eyes more than 30cms

away from the lens. Prolonged viewing of the laser within

30cms may damage your eyesight.

9. Cautions in handling the optical pickup

The laser diode of the optical pickup can be damaged by

electrostatic charge caused by your clothes and body. Make

sure to avoid electrostatic charges on your clothes or body,

or discharge static electricity before handling the optical

pickup.

Before repair or inspection, make sure to follow the

instructions so that customers and Engineers in

charge of repair or inspection can avoid suffering

any risk or injury.

1. Use specified parts.

The system uses parts with special safety features against

fire and voltage. Use only parts with equivalent character-

istics when replacing them.

The use of unspecified parts shall be regarded as remod-

eling for which we shall not be liable. The onus of product

liability (PL) shall not be our responsibility in cases where

an accident or failure is as a result of unspecified parts

being used.

2. Place the parts and wiring back in their original positions

after replacement or re-wiring.

For proper circuit construction, use of insulation tubes,

bonding, gaps to PWB, etc, is involved. The wiring connec-

tion and routing to the PWB are specially planned using

clamps to keep away from heated and high voltage parts.

Ensure that they are placed back in their original positions

after repair or inspection.

If extended damage is caused due to negligence during

repair, the legal responsibility shall be with the repairing

company.

3. Check for safety after repair.

Check that the screws, parts and wires are put back se-

curely in their original position after repair. Ensure for safety

reasons there is no possibility of secondary ploblems around

the repaired spots.

If extended damage is caused due to negligence of repair,

the legal responsibility shall be with the repairing company.

SYSTEM CHECK

The first time this unit is turned on after the wire connections

are completed, it must be checked what equipment is con-

nected. When the power is turned on,

SYSTEM CHK

and

Push POWER

appear in the display alternately, so

press the [FUNC] button. The system check starts within

the unit. When the system check is complete, press the

[FUNC] button again.

ERROR DISPLAYS

If an error occurs, one of the following displays is displayed.

Take the measures described below to eliminate the problem.

9-1. Laser diode

The laser diode terminals are shorted for transporta-

tion in order to prevent electrostatic damage. After

replacement, open the shorted circuit. When remov-

ing the pickup from the mechanism, short the

terminals by soldering them to prevent this damage.

9-2. Actuator

The actuator has a powerful magnetic circuit. If a

magnetic material is put close to it. Its character-

istics will change. Ensure that no foreign sub-

stances enter through the ventilation slots in the

cover.

9-3. Cleaning the lens

Dust on the optical lens affects performance. To

clean the lens, apply a small amount of isopropyl

alcohol to lens paper and wipe the lens gently.

Digital wiring

When the optical digital cable is connected to or discon-

nected from this set later, press the function button while

holding down direct buttons [1] and [6] with the power OFF

to perform a system check.

Though pressing the reset button also performs a system

check, the contents of memory will be erased completely in

this case.
